@Alban_de_Chasteigner gave me a solution for the 0 values appearing on a dimension line. However, this didn’t quite work for me since it didn’t get back some of the references for the newly created dimension line.
Like Viktor says, this happens if you have several references back to back on the same line. That’s why the 0’s are appearing since there is 0 distance between those references. Try to filter your list by getting one of those elements on the same axis value.
